How long until the Check Engine light turns off after messing with the car battery?

You run it over to the local auto parts place and have it checked for free or GOOGLE "how to test a charging system" and "poor mans load test" Run along now.

Probably get a new battery, the lights get dim because the defrost is the number 1 electrical system that uses alot of energy.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
